The HVDC Qinghai-Tibet, Qinghai-Tibet Networking Project, or Qinghai-Tibet Interconnection Project (Chinese: 青藏联网工程) began operation in December 2011, extending from Xining in Qinghai Province in the east to Lhasa in Tibet in the west. Tibet, rich in hydropower resources, serves as a crucial energy relay base for the "West-East Electricity Transmission" initiative (Chinese: 西电东送).[1] However, the region has faced significant challenges, including severe power shortages during the winter and difficulties in consuming excess power during the water-abundant summer months.[2] The commissioning of the Qinghai-Tibet Networking Project has alleviated Tibet's energy bottleneck, fundamentally resolving its long-standing power supply issues.[3]

The Qinghai-Tibet Networking Project is the world's highest-altitude and longest DC transmission line traversing permafrost regions.[4][5] The project has a total investment of 13.918 billion RMB.[6][7]
